Acquired immune deficiency syndrome
- 3. CHainof Infection InfectiousAgent- Human Immunodeficiency Virus Reservoir/Source- Blood or Body Fluids Portal of Exit- Human Blood, Semen, Vaginal Secretions, or Breast Milk
- 4. Mode of Transmission- through direct contact with infected blood or body fluids Portal of Entry- non-intact skin that can occur through unprotected sex, injecting drug use, and rarely splashing onto mucous membranes SusceptibleHost- person infected with HIV
- 6. Treatment, NOT Cure There is no cure for HIV, but there are treatments to enable most people with the virus to live a long and healthy life. EmergencyHIV drugs • If you think you have been exposed to the virus within the last 72 hours (three days), anti-HIV medication may stop you becoming infected. • For it to be effective, the medication, called post-exposure prophylaxis or PEP, must be started within 72 hours of coming into contact with the virus. • The quicker PEP is started the better, ideally within hours of coming into contact with HIV. The longer the wait, the less chance of it being effective.
- 7. If you test positive • If you are diagnosed with HIV, you will have regular blood tests to monitor the progress of the virus before starting treatment. • You will not normally need to start treatment until the virus has begun weakening your immune system. • The aim of the treatment is to reduce the level of HIV in the blood and prevent or delay any HIV- related illnesses. • If you are on HIV treatment, the level of the virus in your blood is generally very low and it is unlikely that you will pass HIV on to someone else
- 8. Antiretroviral drugs • HIV is treated with antiretrovirals (ARVs), which work against the HIV infection by slowing down the spread of the virus in the body. • A combination of ARVs is used because HIV can quickly adapt and become resistant to one single ARV. • Patients tend to take three or more types of ARV medication. This is known as combination therapy or antiretroviral therapy (ART).
- 9. PREVENTION • The eradication of AIDS is based on prevention rather than cure: this means education and action. • Use a new condom every time you have sex. • Consider the drug Truvada. • Tell your sexual partners if you have HIV. • Use a clean needle. • If you're pregnant, get medical care right away. • Consider male circumcision.
